OF AKRON, OHIO, A CORPORATION OF VAPOR LAMP.

Application filed July 21,

The present lnvention relates to vapor lamps wherein a fluid fuel isvaporized and mixed with air and burned.

One of the'objects of the invention is to provide a construction whereinthere is employeda generatorof relatively large ca-' pacity and arrangedin series therewitha generatorof smaller capacity, the generator .ofsmaller capacity permitting the application ofa small amount of heat forthe-put pose of generating suflicient vapor to enable the ignition V Afurther object is to provide a construction wherein the auxiliaryvaporizer ofsmall capacity is directly carried by the vaporizer oflarger capacity and is detachably secured thereto.

'A further object of the invention is to provide aconstruiction whereinboth themain generator and the auxiliary generator are removably carriedby the lamp structure so that they may be assembled. and disassem; bledwith respect to the'lamp as a unitary structure. I

A further object of the invention is to provide a construction wherebythe air which is mixed with the vaporized fuel is taken from a pointaway from the burners thereby insuring a supply of fresh air for thevaporizer and excluding the hot burnt air from the inantles. v

A further object is to provide a construction whereby the tube whichconducts air to,

the bunsen portion of the lamp is movable so as to permit exposure ofthe vapororifice which co-ope'ra'tes with the bunsen, therebypermitting. cleaning of the aforesald orifice.

Other objects of the invention will appear more at large as thedescription proceeds.

Reference should be had to the accompanying drawings forming a part ofthis specification, wherein Fig. 1 is an elevation of a lampembod'yingthe invention, certain portions being shown in section; Fig. 2is a front elevatio'ii' of a portion of the lamp;

Specification of Letters Patent.

1919. set-a1 No. eiaief Fig. 3 is an elevation of an auxiliarygenerator. used in connection with the lamp Fig. 4 is a section on theline 4l4t of Fig. 2.

Referring to the drawings, l'indicates a base which serves as areceptacle for containing fluid fuel, either gasoline, kerosene orsimilar fuel oil. Communicating with the base'receptacle 1 is a tube 2which serves as a generator tube, as will later be explained.Communication between the base receptacle 1' and the generator 2 iscontrolled bya suitable valve mechanism which is indicated at 3.

The generator 2 is more or less completely filled with a loose packlng4, of wire gauze or other suitable material which acts as a strainerretaining the particles of carbon or. heavier substances which areformedby "the vaporizing of thefiuid fuel.

One end of the tube 2 is threaded into what may be termeda yoke 5 .Thisyoke provides an open space 6.. The upper part of the yoke 5- isthreaded and receives a jam screw 7 which jam screw extends through anopening in a portion .of the head 8. which'thus extends through theopening'in the head 8 is threaded as indicated at? and is adapted toreceive a ring nut 9 which when tightened securely holds the am nut withrespect to the head and by so much definitely positions and locates thegenerator tube'2 with respect to the head 8. The ring nut'has a ringportion 9 which serves as a convenient finger grip for the purpose ofturning the ring nut 9 and also'serves' as a support where it is desiredto suspend or hang the lamp.

The auxiliary generator tube is shown more particularly in Fig. 3 andcomprises a tube 10 of comparatively small diameter. This tube isprovided with a series of annular convolutions 11 and one end of thetube terminates in a fixture 12, which fixture has an extending portion12" and a flange like portion 12". In the fixture l2 there is formed anorifice such as indicated at 12 in Fig. 1, this-orifice being muchsmaller in diameter than the diameter of the'pipe 1.0.

To the other end of the pipe 10 is secured a head 13, which head ishollow and has an opening 13 The lower portion of the head.

The portion the slanting portion 13 of the head 13 cooperates with theopen end of the generator tube 2.-

In order to hold the generator tube in position, the jam nut 7 engageswith the head 13, thereby securely fixing and holding it with respect tothe generator tube 2.

The fixture 12 which is carried by the tube 10 is adapted to cooperatewith thetube which is known as a Bunsen tube. This tube at its lower endis provided with one or more orifices which is indicated at 16. Thelower end of the tube 15 is open and is adapted to receive the fixture12. The tube 15 has an end memberl? provided with a central opening andinto this opening the portion 12 of the fixture 12 extends, the flange12 engaging with the outer side of the member. 17.

- The Bunsen tube 15 at. its-upper end is secured in a suitableopeningin the head 8 which head is hollow, thereby providing a chamber withinthe head. Depending from the headare tubes18'and'19. These. tubes atwhen the fluid ,fuel

, their lower end areadaptedto receive and supportmantles 20. r

thetubes 18. and .19 is such that the mantles 20 lie upon both sides ofthe generator tube 2 so that this eneratorjtube is heated when thevaporized uel and a r is burnin 4 at the. mantles 20 .ff It will furtherbe note that the auxiliary generator tube '10 isso positioned that italso extends. between the mantles 2() so that the auxiliary generator.tube is heated 4 p and airare burned at the mantles 20. 1

Of necessity the Bunsen tube 15. is located 1 adjacent the mantles andunless; some other way is provided, the air. supplied to the Bunsen tubeand passing through the orifices 16 w'ould'be the hot burnt airmore orless directly emanating from the mantles 2O. This is undesirable and inorder to provide and insure comparatively cool and fresh air forthe'Bunsen-tube, a tube 22 is provided which has an opening throughwhich the Bunsen tube 15 extends. The fit of the tube22 upon the Bunsentube 15 is an easy-fit so that the tube 22 may slide.

Furthermore, the tube 22 is of slightly greater diameter than the Bunsentube 15 so that air-passing through the tube 22, may

circulate around thetube 15 andv supply air to all the orifices in theBunsen tube. end of the tube 22 which is adjacent the Bunsen tube isclosed by .a plate 22.

When it is necessary or desirable to clean 7 the orifice 12, this may beeasily accomplished by sliding the tube 22 along the Bunsen tube 15,thereby exposing an orifice in the Bunsen'tube and permitting theinsertion of a small wire into the orifice 12.

In startin the lamp, amatch is applied to the auxi iary generator 10,preferably at the coiled portion 11 thereof, thenthe the lamp.

WVhen the vapor at the mantles is' ignited, heat incident to the vaporburning at the mantle-s is imparted to the generator tube 2, so thattheprincipalyaporizing effect is obtained within the tube 2 but will alsobeapparent that as the vaporized:

fuel passes through the smaller tube 10 it isfurther heated so thatwhenthe fluid.
